More serious competition for air service to the Bay of Islands appeared in January 1975 when Mount Cook Airlines introduced a Britten Norman Islander service to Kerikeri replacing the Grumman Goose service to Paihia. Undoubtedly this had an effect on Air North’s Northland service. Meanwhile the company were planning to introduce a 15 seat De Havilland Heron to service the growing demand on the Auckland-Rotorua service. The Kaikohe run was operated in the middle of the day as an extension the service from Rotorua. The Heron was introduced to the Kaikohe service from December 1975.
